  14. 14. Thick LUNs • Capacity of a thick LUN, is distributed equally across the disks in the pool on which you create the LUN  This behavior changes once data is added from hosts and additional disks are added to the Pool  Incoming data will be added to the new disks only until all disks are equally populated again • Capacity of a thick LUN, is the same as the user capacity that the server’s operating system sees • A thick LUN uses slightly more capacity than the amount of user data written to it due to the metadata • A thick LUN can never run out of space.Copyright © 2011 EMC Corporation. All Rights Reserved. Block Storage Provisioning and Management 14
  15. 15. Thin LUNs • Supported for storage systems with the Thin Provisioning enabler • Competes with other LUNs in the pool for the pool’s available storage • Capacity of the thin LUN that is visible to the server is independent of the available physical storage in the pool • A thin LUN can run out of disk space if the pool to which it belongs runs out of disk space • A thin LUN uses slightly more capacity than the amount of user data written to it due to the metadataCopyright © 2011 EMC Corporation.
